Abstract

A method and apparatus for adhesively bonding together in edge abutting relationship two sheets of woven, felted, or other textile material such as carpet using a joining tape which includes a removable electrically conductive foil and layer of heat so/tenable adhesive. The control circuit maintains the adhesive in a tacky state while the abutting edges which overlap the tape are adjusted as required to form the desired joint.

Description

DK 161663 BDK 161663 B

Den foreliggende opfindelse angår et bånd af den i indledningen til krav 1 angivne art til at forbinde materialeplader, såsom materialer til gulvbelægning, f.eks. tæpper, syntetiske belægninger på sportbaner og andre plademateriale, som lægges 5 således, at de støder sammen kant i mod kant. Opfindelsen angår endvidere en fremgangsmåde til at samle kantdele og en fremgangsmåde til at adskille materialeplader, som tidligere er blevet forbundet ved en brug af et sådant bånd med et klæbemiddel, som kan blødgøres af varme.The present invention relates to a strip of the kind set forth in the preamble of claim 1 for joining material sheets such as flooring materials, e.g. carpets, synthetic coatings on sports fields and other sheet material, which are laid 5 so that they bump edge to edge. The invention further relates to a method of assembling edge portions and a method of separating sheets of material which have previously been joined by the use of such a tape with an adhesive which can be softened by heat.

Selv om opfindelsen kan anvendes til at samle og adskille mange forskellige former for materialeplader, inklusiv stoffer, vægbeklædningsmaterialer og lignende, vil opfindelsen i det følgende blive beskrevet i forbindelse med samling og ad-15 skillelse af tæppematerialer.Although the invention can be used to assemble and separate many different types of material sheets, including fabrics, wall coverings, and the like, the invention will be described below in connection with the assembly and separation of carpet materials.

Det er velkendt at forbinde ved siden af hinanden liggende sammenstødende kanter af tæpper med et tæppebindende bånd, som klæber til tæppes bagklædning med et klæbemiddel, som enten 20 kan være et opløseligt klæbemiddel eller i den senere tid et klæbemiddel, som blødgøres af varme.It is well known to associate adjacent adjacent edges of carpets with a carpet binding band which adheres to the backing of the carpet with an adhesive which may either be a soluble adhesive or, more recently, an adhesive which is softened by heat.

I et kendt system anvendes et tæppebindende bånd, som består af et lag af materiale, f.eks. papir, et lag af stof, vævet 25 materiale eller et andet forstærkningsmateri ale og et øvre lag af en klæbemiddelforbindelse, som kan blødgøres med varme, idet arten og tykkelsen af klæbemiddelforbindelsen er således, at der dannes en klæbende binding mellem stoffet, det vævede materiale eller forstærkningsmaterialet og undersiden af. et 30 tæppemateriale, når tapen eller klæbebåndet anvendes i en operation, ved hvilken varme påføres tæppet og klæbemidlet med et opvarmet "jern", som bevæges langs den søm, som skal forbin des. Når tæppematerialet presses ind imod det klæbende lag, som er blødgjort af varmen, og varmekilden fjernes, stivner 35 klæbemidlet, således at tæppets kanter bindes til stoffet, det vævede materiale eller andet forstærkningsmateriale.In a known system, a carpet binding band is used which consists of a layer of material, e.g. paper, a layer of fabric, woven material or other reinforcing material ale and an upper layer of an adhesive that can be softened with heat, the nature and thickness of the adhesive compound being such that an adhesive bond is formed between the fabric, the woven material or the reinforcing material and underside of. a blanket material when the tape or adhesive tape is used in an operation in which heat is applied to the blanket and adhesive with a heated "iron" which moves along the seam to be joined. When the carpet material is pressed against the adhesive layer softened by the heat and the heat source is removed, the adhesive hardens so that the edges of the carpet are bonded to the fabric, woven material or other reinforcing material.

Australsk patent nr. 464.878 beskriver et tæppebindende bånd, som består af et lag varmeisolerende materiale, som f.eks. papir, et lag af metalfolie og et øverste lag af et bånd af en klæbemiddel forbi ndelse, som skal blødgøres af varme, hvor ar-10 ten og tykkelsen af klæbemiddel forbi ndel ses-båndet er sådan, at der dannes en klæbende binding med undersiden af et tæppe-materiale, når båndet anvendes ved en operation, ved hvilken tæppemater i a let presses imod det med varme bl ødgjorte klæbende lag. Klæbemiddelforbindelsen blødgøres ved at lede en elek-15 trisk strøm gennem metalfolien. Et vævet tekstilmateriale kan eventuelt være indlagt i klæbemiddelbåndet for at forstærke strimmelen.Australian Patent No. 464,878 discloses a blanket binding strip consisting of a layer of heat insulating material such as e.g. paper, a sheet of metal foil and a top layer of a tape of an adhesive bond to be softened by heat, the nature and thickness of adhesive past the adhesive tape being such as to form an adhesive bond with the underside of a blanket material when the tape is used in an operation in which blanket mats are easily pressed against the hot, softened adhesive layer. The adhesive compound is softened by passing an electric current through the metal foil. A woven textile material may optionally be embedded in the adhesive tape to reinforce the strip.

I US patentskrift nr. 4.416.713 er beskrevet en forbedret me-20 tode og apparat til at forbinde pladematerialer, hvori den elektriske strøm gennem metalfolie styres for derved at styre graden af blødgøring af klæbemidlet for at gøre det muligt at rette tæppeforbindelseslinien ind efter en ret linie, før forbindelsen fastgøres til den bindende strimmel.U.S. Patent No. 4,416,713 discloses an improved method and apparatus for connecting sheet materials in which the electrical current through metal foil is controlled, thereby controlling the degree of softening of the adhesive to enable the carpet joining line to be aligned with a straight line before attaching the connection to the binding strip.

Medens de tidligere beskrevne tæppeforbindelsesmetoder sædvanligvis giver en relativ fast samling mellem kanterne af de til stødende plader af tæppemateriale, har det vist sig, at omkostningerne ved den elektrisk opvarmede tæppebindingsstrimmel 30 inklusiv den indbyggede metalfoliestrimmel er relativ høje.While the previously described carpet bonding methods usually provide a relatively firm joint between the edges of the abutting sheets of carpet material, it has been found that the cost of the electrically heated carpet bonding strip 30 including the built-in metal foil strip is relatively high.

Det syntes nødvendigt at binde metalfoliestrimmelen til de andre lag, som danner den tæppebindende strimmel, dvs. papirunderlaget, de forstærkende og klæbende materialer for at sikre en jævn opvarmning af klæbemidlet, og at strimmelen ligger 35 nøjagtigt på en ret linie under kantdelene af det tæppemateriale, som skal forbindes. Det har imidlertid nu vist sig, at det ikke er nødvendigt at fastgøre metalfolielaget til de an- 3It seemed necessary to bond the metal foil strip to the other layers forming the blanket binding strip, i.e. the paper substrate, the reinforcing and adhesive materials to ensure even heating of the adhesive, and that the strip lies exactly on a straight line below the edge portions of the carpet material to be bonded. However, it has now been found that it is not necessary to attach the metal foil layer to the other 3

dre materialelag i tæppebi ndingsstri mmelen, og at bedre og mere økonomiske resultater kan opnås med strimmelen og fremgangsmåden ifølge den foreliggende opfindelse.and that better and more economical results can be obtained with the strip and method of the present invention.

5 Nogen tid efter at et tæppe er lagt, opstår der ofte en vis udstrækning, som gør det nødvendigt, at tæppet lægges om, hvis det skal bevare sit bedste udseende og de bedste slidegenskaber. En sådan omlægning kræver sædvanligvis en adskillelse og en nyforbindelse af sammenstødende kanter, for at de igen skal 10 ligge på linie. Tæppekantde1e, som har været forbundet med en strimmel ved anvendelse af et opvarmet jern for at smelte et klæbemiddel, som kan blødgøres af varme, er til dels vanskelige at adskille og at fjerne den forbindende strimmel fra.5 Some time after a blanket is laid, a certain extent often occurs, which necessitates re-laying of the rug in order to maintain its best appearance and wear characteristics. Such a rearrangement usually requires a separation and a new connection of adjacent edges in order for them to again be aligned. Carpet edges which have been connected to a strip using a heated iron to melt an adhesive which can be softened by heat are, in part, difficult to disassemble and remove the connecting strip.

15 Ved den hidtil kendte fremgangsmåde til at forbinde tæppekanter ved anvendelse af en elektrisk opvarmet tæppeforbindelsesstrimmel varieres den elektriske strøm, som skal passere gennem folien, for at klæbemidlet kan blødgøres, med omgivelsernes temperatur og varieres endvidere, efterhånden som tempera-20 turen af folien forøges. Sådanne variationer kan medføre en startstrøm gennem folien, som overbelaster det elektriske forsyningskredsløb, hvortil styreapparatet er forbundet.15 In the prior art method of connecting carpet edges using an electrically heated carpet connection strip, the electric current to pass through the foil so that the adhesive can be softened is varied with ambient temperature and further varied as the temperature of the foil increases. . Such variations may cause a starting current through the foil which overloads the electrical supply circuit to which the controller is connected.

Det er derfor formålet med den foreliggende opfindelse at ti 1 -25 vejebringe en forbedret fremgangsmåde til at forbinde plademateriale i kant imod kant-relation, hvorved forbindelsen kan ske relativ hurtigt, enkelt og på økonomisk måde.It is therefore the object of the present invention to provide an improved method of connecting edge-to-edge plate material, whereby the connection can be made relatively quickly, simply and economically.

Det er endvidere tilsigtet med opfindelsen at tilvejebringe. en 30 fremgangsmåde til at adskille en tæppeforbindende tape, som tidligere er blevet forbundet til tæppekantde!ene med et klæbemiddel, som kan blødgøres med varme.It is further an object of the invention to provide. a method of separating a carpet joining tape previously connected to carpet edges with an adhesive which can be softened with heat.

Det er endvidere tilsigtet at tilvejebringe et bånd, som kan 35 anvendes ved samlingen af tæppekantdele og ved adskillelsen af tæppebindende bånd fra sådanne kantdele.It is further intended to provide a tape which can be used in the assembly of carpet edge parts and in the separation of carpet binding bands from such edge parts.

Ifølge opfindelsen tilvejebringes et bånd til brug ved samling eller adskillelse af kanter af et tæppe eller et andet plade-materiale, der støder tæt sammen, hvilke bånd omfatter en aflang strimmel af metalfolie, en strimmel af et under1agsmate-5 riale, et pladesamlende materiale, og et klæbemiddel, som blødgøres ved varme, og hvor strimlen af metalfolie har en tværdimension, der er mindre end eller lig med tværdimensionen af underlagsmaterialet, og hvor metalfolien har en tykkelse, således at en elektrisk strøm, som ledes gennem metalfolien, 10 vil bevirke en opvarmning af denne til en temperatur, der i hvert fald er tilstrækkelig til at blødgøre klæbemidlet på pladesamlingsmaterialet for at binde pladesaml emateri alet til pladematerialet, idet metalfolien og underlags-materialet er adskilt fra pladesamlingsmaterialet og klæbemidlet, idet me-15 talfolien og underlagsmaterialet er forbundet til hinanden, og idet metalfolien og underlagsmaterialet kan fjernes fra de samlede kanter af pladematerialet til genbrug, og idet metalfolien og underlagsmaterialet danner et skilleelement eller skilleværktøj til adskillelse af tidligere samlede plademate-20 r i a 1e r.According to the invention, a tape is provided for use in joining or separating edges of a blanket or other sheet material which is adjacent to each other, which strip comprises an elongated strip of metal foil, a strip of a substrate material, a sheet gathering material, and an adhesive which is softened by heat and wherein the strip of metal foil has a cross-dimension less than or equal to the cross-section of the substrate material and wherein the metal foil has a thickness such that an electric current passed through the metal foil will effect heating it to a temperature sufficient at least to soften the adhesive on the sheet metal material to bond the sheet metal material to the sheet material, the metal foil and the substrate being separated from the sheet metal material and the adhesive, the metal foil and the substrate material being and the metal foil and the backing material can be removed from each other assembled edges of the sheet material for reuse, and the metal foil and substrate forming a separating element or separator for separating previously assembled sheet mats in a first year.

Derved opnås at metalfolien kan genbruges.This ensures that the metal foil can be recycled.

Metalfoliestrimmelen er fortrinsvis syet på underlagsmateria-25 let, som kan udgøres af crepepapir, kraftpapir eller et andet passende materiale, som har den virkning, i hvert fald delvis at varmeisolere folien fra en underliggende overflade. Det foretrækkes, at folien og underlagsmaterialet stikkes sammen ved anvendelse af en bomulds- eller glasfibertråd.The metal foil strip is preferably sewn onto the backing material which may be made of crepe paper, kraft paper or other suitable material having the effect, at least in part, of insulating the foil from an underlying surface. It is preferred that the foil and substrate material be stitched together using a cotton or fiberglass thread.

Ifølge opfindelsen anvendes endvidere en fremgangsmåde til at samle sammenstødende kantdele af væv, filt eller andet pladeformet tekstilmateriale ved brug af et stykke tekstil eller bånd omfattende et klæbemiddel, som blødgøres af varme, og et 35 forstærkningsmateriale, hvilken fremgangsmåde omfatter at placere det klæbende tekstilstykke eller klæbebåndet i berøring med de sammenstødende kantdele af tekstilmaterialet såle- 5According to the invention, a method is also used for gathering adjacent edge portions of fabric, felt or other plate-shaped textile material using a piece of textile or tape comprising a heat softened adhesive and a reinforcing material which comprises placing the adhesive fabric piece or the adhesive tape in contact with the adjacent edge portions of the textile material 5

des, at det klæbende tekst ilstykke eller klæbebåndet overlapper de sammenstødende kanter, at lede en elektrisk strøm igennem en metalfolie, der ligger tæt op ad det klæbende tekstil eller klæbebåndet til frembringelse af varme i metalfolien og 5 dermed i det klæbende tekstilstykke eller klæbebåndet, at styre strømstyrken således, at den frembragte varme i hvert fald blødgør klæbemidlet, at trykke de sammenstødende kantdele af pladerne ned imod det klæbende tekstilstykke eller klæbebåndet for at klæbe det fast 10 til kantdelene, og at standse strømmen for at bevirke, at klæbemidlet stivner og binder det forstærkende materiale til kantdelene, idet metalfolien er en strimmel, der placeres i tæt berøring med det klæbende tekstilstykke eller klæbebåndet, men uden at være 15 fastgjort til det klæbende tekstilstykke eller klæbebåndet, hvorefter der på i og for sig kendt måde ledes elektrisk strøm gennem metalfoliestrimmelen, og at metalfoliestrimmelen fjernes fra berøring med det klæbende tekstilstykke eller klæbebåndet.i.e., the adhesive text lining or adhesive tape overlaps the abutting edges, passing an electrical current through a metal foil which is close to the adhesive textile or adhesive tape to generate heat in the metal foil, and thus in the adhesive textile or adhesive tape; controlling the current so that the heat generated at least softens the adhesive, depresses the adjacent edge portions of the sheets against the adhesive textile or adhesive tape to adhere it to the edge portions, and to stop the current from causing the adhesive to stiffen and bind the reinforcing material for the edge parts, the metal foil being a strip placed in close contact with the adhesive textile or adhesive tape, but without being attached to the adhesive textile or adhesive tape, after which electrical current is known in a manner known per se. the metal foil strip, and that the metal foil strip is fucking is removed from contact with the adhesive fabric or adhesive tape.

20 I den foretrukne udførelsesform er den anvendte metalfolie en folie på båndet til samling og adskillelse, som anvendes i forbindelse med en bindemiddelstrimmel, som udgøres af et tekstilmateriale, et syntetisk plastmateriale, som f.eks. Ty-25 par® {fremstillet af DuPont) eller et andet materiale, som, når det fastgøres til de tilstødende kantdele på tekstilpladerne, vil fastgøre disse plader til hinanden.In the preferred embodiment, the metal foil used is a film on the strip for assembly and separation which is used in conjunction with a binder strip made up of a textile material, a synthetic plastic material such as e.g. Ty-25 par® (made of DuPont) or other material which, when attached to the adjacent edge parts of the textile sheets, will adhere these sheets to each other.

Det ses, at når samlingen er blevet fremstillet korrekt i 30 overensstemmelse med fremgangsmåden ifølge opfindelsen, fjer nes båndet til samling og adskillelse under den dannede samling og kan genanvendes igen og igen. Omkostningerne til bånd, som anvendes ved forbindelse af kantdelene af plademateriale, reduceres væsentligt, eftersom størstedelen af strimmelen gen-35 bruges i stedet for, at den efterlades under de kanter, der skal forbindes.It will be seen that when the assembly has been properly manufactured in accordance with the method of the invention, the assembly and separation belt is removed during the assembly formed and can be reused again and again. The cost of ribbons used in connection with the edge portions of sheet material is substantially reduced since most of the strip is reused instead of being left under the edges to be joined.

Ifølge opfindelsen anvises yderligere en fremgangsmåde til at skille et klæbebånd af den art, som er angivet ovenfor, fra sammenstødende kantdele af tekst Πp1 ader, hvilket klæbebånd er klæbet til kantdelene med et klæbemiddel, der kan blødgøres af 5 varme, (a) at klæbebåndet skæres op langs den linie, hvor kantdelene støder sammen, (b) at kantdelene bøjes bort fra hinanden, (c) at en metalfoliestrimmel placeres langs den linie, hvor 10 kantdelene støder sammen, (d) at fastgøre klæbebåndsdelene på kantdelene til metalfolie-strimmelen, (e) at lede en elektrisk strøm gennem metalfoliestrimlerne for at frembringe varme deri, 15 (-f) at styre strømstyrken således, at den varme, der frembrin ges, er tilstrækkelig til at blødgøre klæbemidlet, og (g) at skrælle de afskårne klæbebånds-dele af kantdelene.The invention further provides a method of separating an adhesive tape of the kind set forth above from adjacent edge portions of text Πp1 veins, which adhesive tape is adhered to the edge portions by an adhesive which can be softened by heat, (a) that the adhesive tape cut along the line where the edge portions collide, (b) the edge portions bend apart, (c) place a metal foil strip along the line where the edge portions collide, (d) attach the adhesive tape portions to the edge portions of the metal foil strip. (e) conducting an electric current through the metal foil strips to generate heat therein, (f) controlling the current so that the heat generated is sufficient to soften the adhesive, and (g) peel off the cut offs. adhesive tape portions of the edge portions.

Ifølge denne del af opfindelsen foretrækkes det således, at 20 metalfoliestrimmelen omfatter båndet til samling og adskillelse, som beskrevet tidligere.According to this part of the invention, it is preferred that the metal foil strip comprises the band for assembly and separation, as previously described.

Den strøm, som ledes gennem metalfolien, kan styres manuelt eller automatisk af apparatur beskrevet i det førnævnte ameri-25 kanske patentskrift. Når dette apparat anvendes til at for binde sammenstødende kanter af plademateriale, styres den strøm, der ledes gennem meta1foli el åget for at frembringe en varme, som vil blødgøre klæbemidlet, og justeringer mellem kanterne af pladematerialet kan foretages, hvorefter tempera-30 turen hæves således, at klæbemidlet smeltes til en bindingstemperatur.The current passed through the metal foil can be controlled manually or automatically by apparatus described in the aforementioned United States patent. When this apparatus is used to bond adjacent edges of sheet material, the current which is passed through the metal foil or yoke is controlled to produce a heat which will soften the adhesive, and adjustments between the edges of the sheet material can be made and the temperature thus raised. , the adhesive is melted to a bonding temperature.

Det har vist sig, at den strøm, der går i metalfolien, og den varmevirkning, der derved skabes, falder, når temperaturen i 35 folien stiger. Det bevirker, at sammenføjningsoperationen bliver langsommere. Det er derfor hensigtsmæssigt at anvende et apparat, som indbefatter en bane, som har et forstærknings- 7It has been found that the current flowing in the metal foil and the resulting heat effect decrease as the temperature of the foil rises. This causes the joining operation to become slower. It is therefore advisable to use an apparatus which includes a web having a reinforcement.

Opfindelsen skal i det følgende forklares nærmere ud fra nogle 15 udførelsesformer og under henvisning til de ledsagende tegninger, hvor fig. 1 viser en udførelsesform af et samle- og skillebånd ifølge den foreliggende opfindelse, 20 fig. 2 fremstilling af et samle- og skillebånd ifølge en anden udførelsesform af opfindelsen, fig. 3 et perspektivbillede, der viser et apparat til brug ved 25 fjernelsen af båndet til samling og adskillelse under de forbundne kantdele af tæppet, og fig. 4 et kredsløbsdiagram, der viser et styreapparat til at udøve fremgangsmåden ifølge opfindelsen.The invention will now be explained in more detail with reference to some embodiments and with reference to the accompanying drawings, in which fig. 1 shows an embodiment of an assembly and separating belt according to the present invention; FIG. 2 shows an assembly and separating belt according to another embodiment of the invention; FIG. 3 is a perspective view showing an apparatus for use in removing the tape for assembly and separation under the connected edge portions of the blanket; and FIG. 4 is a circuit diagram showing a control apparatus for practicing the method according to the invention.

Som vist i fig. 1 omfatter båndet til samling og adskillelse ifølge opfindelsen et underlag 12, som kan bestå af papir, såsom crepepapir eller kraftpapir. En metalfoliestrimmel 14 er fastgjort til underlaget 12 med løse sting gennem folien 14 og 35 underlaget 12 med en tråd af bomuld, glasfiber eller et andet materiale, som i hovedsagen ikke påvirkes af den varme, som frembringes i folien 14. I fig. 1 er folien 14 vist som fast- 8As shown in FIG. 1, the assembly and separation band of the invention comprises a support 12 which may consist of paper such as crepe paper or kraft paper. A metal foil strip 14 is attached to the substrate 12 with loose stitches through the foil 14 and 35 the substrate 12 with a cotton, fiberglass or other material thread which is substantially unaffected by the heat generated in the foil 14. In FIG. 1, the film 14 is shown as solid 8

DK 161663 BDK 161663 B

gjort til underlaget 12 med to rækker af sting 16, selv om det er klart, at ethvert antal rækker af sting kan anvendes.made to the substrate 12 with two rows of stitches 16, although it is clear that any number of rows of stitches can be used.

Papirunderlaget 12 danner et bærerlag for folien 14 og virker 5 som en varmeisol ator mellem folien og enhver underliggende overflade, hvorpå strimmelen anvendes. Papirstrimmelen har en bredde, der mindst er lig med bredden af folien 14, og folien har en tykkelse, som, når en elektrisk strøm ledes igennem folien, vil bevtrke, at temperaturen i folien stiger, i hvert 10 fald til smeltepunktet for et klæbemiddel, som kan blødgøres med varme.The paper substrate 12 forms a support layer for the foil 14 and acts as a heat insulator between the foil and any underlying surface on which the strip is applied. The paper strip has a width at least equal to the width of the foil 14, and the foil has a thickness which, as an electric current is passed through the foil, will cause the temperature of the foil to rise, at least 10 to the melting point of an adhesive. which can be softened with heat.

I fig. 2 er i et plant billede vist en fremgangsmåde til fremstilling af en modificeret form for et bånd til samling og 15 adskillelse ifølge den foreliggende opfindelse. I denne udførelse er foliestrimmelen opdelt i to side om side placerede fol iesektioner 17 og 18, som hver især er syet på underlags-strimmelen 12 med to syninger 16.In FIG. 2 is a plan view showing a method of producing a modified form of a band for assembly and separation according to the present invention. In this embodiment, the foil strip is divided into two side-by-side foil sections 17 and 18, each of which is sewn onto the backing strip 12 with two stitches 16.

20 Ved fremstilling af strimmelen i denne udførelsesform tilføres en foliestrimmel 14 og en underlagsstrimmel 12 oven på hinanden til en symaskine med flere synåle 19, som frembringer stikningerne 16. En kniv 21 er fastgjort foran nålene 19 for at opdele og adskille foliestrimmelen 14 i de to foliesektio-25 ner 17 og 18, før disse sektioner syes på underlagsmaterialet 12. Det ses derfor, at den resulterende samling og/eller adskillelse har adskile foliesektioner 17 og 18, som er syet til underlaget 12, og som danner en samling og adskillelse, der kan anvendes til relativt lange tæppesømme, som det vil fremgå 30 i det følgende.In preparing the strip in this embodiment, a foil strip 14 and a backing strip 12 are superimposed on top of each other a sewing machine 19, which produces the stitches 16. A knife 21 is secured in front of the needles 19 to divide and separate the foil strip 14 into the two foil sections 17 and 18 before these sections are sewn onto the backing material 12. Therefore, it is seen that the resulting assembly and / or separation has separate foil sections 17 and 18 which are sewn to the substrate 12 and which form an assembly and separation. which can be used for relatively long carpet seams, as will be seen below.

Strimmelen ifølge opfindelsen kan anvendes, både til at forbinde tilstødende kantdele af tæpper og til at fjerne et tæppebindende bånd, som tidligere er fastgjort til tildstødende 35 kantdele af et tæppe ved hjælp af et klæbestof, som kan blødgøres af varme. Ved udøvelsen af den foretrukne fremgangsmåde ifølge opfindelsen placeres samlingen og adskillelsen ifølge 9The strip of the invention can be used both to connect adjacent edge portions of carpets and to remove a carpet binding band previously attached to adjacent edge portions of a blanket by means of an adhesive which can be softened by heat. In the practice of the preferred method of the invention, the assembly and separation according to 9 are placed

opfindelsen under et tæppebindende bånd med et klæbemiddel, som kan blødgøres af varme. Den tæppebindende strimmel omfatter fortrinsvis et forstærkningsmateriale som f.eks. et vævet materiale eller et ikke-vævet materiale, såsom Typar eller et 5 andet passende forstærkningsmateriale, som, når det bindes til tæppekantdelene, fastholder disse kantdele i tilstødende relation. Klæbemidlet er fortrinsvis et termoplastisk klæbemiddel som f.eks. beskrevet i amerikansk patentansøgning nr. 171.865. Samlings- og adskillelsesstrimmelen og den overliggende tæppede forbindende strimmel er placeret under de tilstødende kantdele af tæppestykkerne, som skal forbindes, således at kantdelene overlapper den forbindende strimmel i hele deres længde, således at kanterne mødes omtrent langs midten af den tæppefor-bindende strimmel. En elektrisk strøm ledes gennem metalfolien 15 i samlings- og adskillelsesstrimmelen for derved at frembringe varme i metalfolien, således at klæbemidlet på den tæppefor-bindende strimmel i hvert fald blødgøres. Når klæbemidlet bliver blødt og klæbende, trykkes tæppedelene let imod den tæppe-forbindende strimmel, og justering af kantdelene kan foreta-20 ges, for at tæppets mønstre kan passes til og for at sikre, at kanterne støder tæt sammen. Strømmen i metalfolien forøges derefter for at frembringe ti 1 strækkel i g varme til fuldstændigt at samle klæbemidlet, hvorefter strømmen standses for, at klæbemi diet kan stivne og dermed fastholde tæppekanterne på 25 den forbindende strimmel.the invention under a carpet binding band with an adhesive which can be softened by heat. The blanket binding strip preferably comprises a reinforcing material such as e.g. a woven material or nonwoven material such as Typar or other suitable reinforcing material which, when bonded to the carpet edge portions, retains these edge portions in adjacent relation. The adhesive is preferably a thermoplastic adhesive such as e.g. disclosed in U.S. Patent Application No. 171,865. The joining and separating strip and the overlying carpet connecting strip are positioned below the adjacent edge portions of the carpet pieces to be joined so that the edge portions overlap the connecting strip throughout their length so that the edges meet approximately along the center of the carpet connecting strip. An electric current is passed through the metal foil 15 in the joint and separation strip to thereby generate heat in the metal foil so as to at least soften the adhesive on the carpet-binding strip. When the adhesive becomes soft and sticky, the carpet parts are lightly pressed against the carpet-joining strip, and adjustment of the edge parts can be made to match the patterns of the carpet and to ensure that the edges bump tightly together. The flow in the metal foil is then increased to produce ten liters in g of heat to completely collect the adhesive, after which the flow is stopped so that the adhesive diet can solidify and thus retain the carpet edges of the connecting strip.

Efter at de tilstødende kantdele af tæppet er fastgjort til forbindelsesstrimmelen, kan samlings- og adskillelsesstrimme-len fjernes neden under sømmen. Dette kan gøres ved simpelthen 30 på langs at trække samlings- og adskillelsesstrimmelen af, men gøres fortrinsvis ved anvendelse af et apparat, vist i fig. 3. Apparatet 22 består af en endeflange 23, en topflange 24 og en skrå styreflange 26. En krum styreplade 27 er monteret oven over og i afstand fra topflangen 24 på benene 28. I brug plac-35 eres styreflangen 26 under tæppet ved den ene ende af tæppesømmen, som sædvanligvis støder op til en væg i det lokale eller lignende, hvori tæppet er blevet lagt på. Endeflangen og 10After the adjacent edge portions of the rug are attached to the connecting strip, the joining and separating strip can be removed below the seam. This can be done by simply pulling the assembly and separation strip longitudinally, but preferably by using an apparatus shown in FIG. 3. The apparatus 22 consists of an end flange 23, a top flange 24 and an oblique guide flange 26. A curved guide plate 27 is mounted above and at a distance from the top flange 24 on the legs 28. In use, the guide flange 26 is placed under the blanket at one end. end of the carpet seam, which is usually adjacent to a wall in the room or the like in which the carpet has been laid. The end flange and 10

topflangen gør det muligt at placere apparatet 22 over ethvert eksisterende tæppekantbånd, som almindeligvis anvendes til at fastgøre tæppet i en given position. Enden af samlings- og adskillelsesstrimmelen føres ind mellem toppen 24 og den krum- , 5 me styreplade 27 og hen over styreflangen 26 for at lade samlings- og adskillelsesstrimmelen blive trukket tilbage ved at påføre et træk i tæppesømmens retning.the top flange makes it possible to place the apparatus 22 over any existing carpet edge band, which is generally used to secure the carpet in a given position. The end of the joint and separation strip is inserted between the top 24 and the curved, 5 guide plate 27 and across the guide flange 26 to allow the joint and separation strip to be retracted by applying a pull in the direction of the carpet seam.

Ved udøvelse af den ovenfor beskrevne fremgangsmåde ledes en 10 elektrisk strøm gennem metalfolien 14 i samlings- og adskillelsesstrimmelen ved at forbinde en elektrisk spænding mellem punkter i afstand fra hinanden langs folien og fortrinsvis til folien, hvor den rager ud fra hver ende af den søm, som skal fremstilles. Ved udøvelse af opfindelsen under brug af sam-15 lings- og adskillelsesstrimmelen, fig. 2, kan en elektrisk spænding tilvejebringes mellem fol iesektionerne 17 og 18 i den ene ende af sømmen, og ved at forbinde en elektrisk kortslutning mellem foliesektionerne 17 i den modsatte ende af sømmen.In carrying out the method described above, an electric current is passed through the metal foil 14 in the joint and separation strip by connecting an electrical voltage between points at a distance from one another along the foil and preferably to the foil where it protrudes from each end of the nail. which must be manufactured. In practicing the invention using the assembly and separation strip, FIG. 2, an electrical voltage can be provided between the foil sections 17 and 18 at one end of the seam, and by connecting an electrical short circuit between the foil sections 17 at the opposite end of the seam.

På denne måde kan relativt store sømlængder fremstilles, uden 20 at der er behov for at anvende lange ledninger til at forbinde en spændingskilde til folien.In this way, relatively large seam lengths can be produced without the need to use long wires to connect a voltage source to the foil.

Samlings- og adski1lelsesstrimmelerne ifølge opfindelsen kan også anvendes til at bistå med fjernelsen af en tæppeforbin-25 dende strimmel fra en tidligere fremstillet forbindelse. Det tæppebindende bånd skæres gennem langs samlingen, tæppets kantdele bøjes tilbage for at tillade, at samlings- og adskillelsesstrimmelen ifølge opfindelsen kan placeres under samlingen. En elektrisk strøm ledes gennem metalfolien 14 i samso lings- og adskillelsesstrimmelen for at frembringe varme til at blødgøre det klæbemiddel, der skal kunne blødgøres af varme, og som forbindet det tæppebindende bånd med tæppekantdele-ne. Når klæbemidlet er tilstrækkeligt blødt eller smeltet, kan delene af forbindelsesbåndet let skrælles af tæppekantdelene, 35 således at kantdelene er klar til på ny at blive forbundet, når man ønsker det.The assembly and peel strips of the invention may also be used to assist in the removal of a carpet-joining strip from a previously manufactured compound. The blanket binding strip is cut through along the joint, the edge portions of the blanket bent back to allow the joining and separating strip of the invention to be placed below the joint. An electric current is passed through the metal foil 14 in the junction and separation strip to produce heat to soften the adhesive that can be softened by heat and which connects the carpet binding band to the carpet edge portions. When the adhesive is sufficiently soft or melted, the portions of the connecting strip can be easily peeled off by the carpet edge portions, such that the edge portions are ready to be re-joined when desired.

Som en hjælp ved fjernelsen af samlings- og adskillelsesstrimmelen efter enten en samlings- eller adski1lelsesopretation er det fordelagtigt, at metalfoliestrimmelen 14 og enhver frilagt del af bagsiden 12 pudres let med et frigørelsespudder, f.eks.To aid in the removal of the assembly and separation strip after either an assembly or separation operation, it is advantageous that the metal foil strip 14 and any exposed portion of the backing 12 be lightly powdered with a release powder, e.g.

5 en talkum. Frigørelsespuderet søger at forhindre, at ethvert klæbende materiale, som måtte strømme ud fra den forbindende strimmel, klæber til folien 14 eller underlaget 12.5 and talc. The release powder seeks to prevent any adhesive material which may flow from the connecting strip from adhering to the film 14 or the substrate 12.

Det er klart, at fremgangsmåden til samling eller adskillelse 10 ifølge den foreliggende opfindelse kan udføres på tilfreds stillende måde under visse omstændigheder uden brug af et underlag 12. Fremgangsmåderne ifølge opfindelsen indbefatter således anvendelsen af en folie aftageligt anbragt under tæppe-kantdelene, uden at der er et under fastgjort til folien.It is to be understood that the method of assembly or disassembly 10 of the present invention can be satisfactorily carried out in certain circumstances without the use of a support 12. Thus, the methods of the invention include the use of a foil removably disposed under the carpet edge portions without is a sub attached to the foil.

Fortrinsvis ved udførelse af samlemetoden ifølge opfindelsen tilvejebringes den elektriske strøm, som sendes gennem metalfolien 14, af et styret apparat, som er indrettet til at blive forbundet til en netspænding, og som tilvejebringer en relativ 2o Tav spænding på metalfolien. Fig. 4 er indgangsspændingen forbundet til indgangsterminalerne 31 og vis en omskifter 33 og en Triac 34 ført til en spændingstransformer 32. Den sekundære vinding 36 giver på udgangen en vekselspænding på ca. 30 volt, som påtrykkes metalfolien 14.Preferably, in carrying out the assembly method of the invention, the electrical current transmitted through the metal foil 14 is provided by a controlled apparatus which is adapted to be connected to a mains voltage and which provides a relative 20o voltage to the metal foil. FIG. 4, the input voltage is connected to the input terminals 31 and show a switch 33 and a Triac 34 lead to a voltage transformer 32. The secondary winding 36 gives an output voltage of approx. 30 volts applied to the metal foil 14.

Udgangsspændingen styres af et Triac-styrekreds1øb, som omfatter en spændingsforsyning 37 via en lille transformer 38, der er forbundet parallelt med den store transformer 32.The output voltage is controlled by a Triac control circuit which comprises a voltage supply 37 via a small transformer 38 connected in parallel to the large transformer 32.

30 En strømtransformer 39 er tilsluttet udgangskredsløbet fra den store transformer 32 for at måle strømmen i udgangskredsløbet. Strømtransformeren 39 giver et signal til en strømtiIbagekob-1 ingsforsstærker 41, som igen driver et fasestyrekreds1øb 42, der er forbundet til Triac'en 34 og styrer affyringen af 35 Triac'en. Udgangssignalet fra strømtilbagekoblingsforstærkeren 41 afhænger af stillingen af en omskifter 43, som kan skiftes mellem en "varme" position 48, en "holde" position 47, en 12A current transformer 39 is connected to the output circuit of the large transformer 32 to measure the current in the output circuit. The current transformer 39 provides a signal to a power feedback amplifier 41 which in turn drives a phase control circuit 42 connected to the Triac 34 and controls the firing of the Triac. The output of the power feedback amplifier 41 depends on the position of a switch 43 which can be switched between a "heat" position 48, a "hold" position 47, a 12

DK 161663 BDK 161663 B

"lav" position 46 og en "afbrudt" position 44. I enhver af "varme", "holde", og "lav" stillingerne justeres affyringen af Triac'en 34 således, at der opnås en forudbestemt udgangsstrøm. Forstærkningen i strømtilbagekoblingsforstærkeren 41 5 afhænger af den valgte styretilstand og af den målte udgangsstrøm, som bestemmes af strømtransformeren 39. Hvis modstanden mellem udgangsterminalerne 52 varierer i overensstemmelse med varierende længder af de metalfoliestrimler, hvortil styreap-paratet er forbundet eller varierer på grund af ændringer i 10 modstanden fremkaldt af temperaturændringer, vil udgangsstrømmen variere, og denne variation afføles af strømtransformeren, som effektivt ændrer forstærkningen af strømtilbagekoblingsforstærkeren for at forøge (eller formindske) udgangsspændingen til, hvad der er forudbestemt for den valgte funktion."low" position 46 and a "disconnected" position 44. In each of the "heat", "hold", and "low" positions, the firing of the Triac 34 is adjusted so as to obtain a predetermined output current. The gain of the current feedback amplifier 41 5 depends on the selected control state and the measured output current determined by the current transformer 39. If the resistance between the output terminals 52 varies according to varying lengths of the metal foil strips to which the controller is connected or varies In the resistance induced by temperature changes, the output current will vary, and this variation is sensed by the current transformer, which effectively changes the gain of the current feedback amplifier to increase (or decrease) the output voltage to that predetermined for the selected function.

15 Styreapparatet er således selvjusterende til opretholdelse af en maksimal udgangsstrøm, uanset variationer i modstanden af metalfoliestrimmelen, der er forbundet mellem udgangsterminalerne 52.Thus, the controller is self-adjusting to maintain a maximum output current, regardless of variations in the resistance of the metal foil strip connected between the output terminals 52.

20 I den udførelsesform, der er vist i fig. 4, er den kraftige spændingstransformer 32 forsynet med en hårdt optrukket eller overviklet primær vinding, som begrænser indgangsstrømmen til en forudbestemt maksimal værdi under opvarmningen, dvs., når omskifteren 43 står i positionen "varme”. Når omskifteren 43 25 skiftes over på "holde" eller "1av"-sti 11 i ngerne, ændres også tilslutningspunktet eller punkterne på den primære vinding. I denne udførelsesform kan apparatet således også anvendes, når netspændingen har en begrænset udgangseffekt, uden at overbelaste nettet.20 In the embodiment shown in FIG. 4, the powerful voltage transformer 32 is provided with a hard pulled or overwrought primary winding which limits the input current to a predetermined maximum value during the heating, i.e. when the switch 43 is in the "heat" position. "or" 1 of "path 11 of the nodes, the connection point or points of the primary winding are also changed. In this embodiment, the apparatus can also be used when the mains voltage has a limited output power, without overloading the mains.
